Not particularly "pretty" cards, but I do like the vintage GE logo on the back. The Hotel Potter card shows that it was made by the Detroit Publishing Co. The bottom card looks like it is from the same, but bears no markings.
The Hotel Potter was completed in 1903 and immediately became a landmark on the Santa Barbara coastline. Sadly it burned to the ground only 18 years later. The Hotel Del Monte was opened in 1880 by Charles Crocker (one of the Big Four that developed the Southern Pacific Railroad). The Del Monte was a favorite of the rich and famous. A young William Randolph Hearst practically lived at the Del Monte.
Mazda was a trademarked name registered by General Electric in 1909 (Thomas Edison formed GE in 1892) for incandescent light bulbs.
Anyone know if the light bulbs in the "Lovelight" series were Edison Mazda bulbs??
